CAR-RJOOF.

QPECIFIOATION forming' part of letters Patent N 0. 718,145, datedJanuary 13, 1903.

Application filed May 19,1902. Serial No. 108,006. (No model.)

To add whom it may concern;

Be it knownthat 1, JAMES J. MCCARTHY, a citizen of the United States,residing at Ohicago, in the county of Cook-and State of Illinois, haveinvented certain new and useful Improvements in Car-Roofs, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates to roofs,and has particularly to do with metallicroofs for cars and other structures.

One of the objects of my invention is to pro vide an improvedconstruction of metallic roof, which will be well adapted for use in eX-.eled, as shown in Figs. 3 and 4, so that they posed situations-that isto say, where the metal roof is not covered by a wooden roof, as isusually the practice in car construction.

A further object is to provide an improved metallic roof which will beso constructed as not to be damaged by wrenching strains-of thecar-body. V

I accomplish these objects as hereinafter described and as illustratedin the drawings.

What I regard as new is set forth .in the claims.

In the accompanying drawings, Figure l is a partial perspectiveviewillustrating my improved car-roof. Fig. 2is a cross-section of aroof embodying my improvements. Fig. 3 is an enlarged detail, being across-sectional view showing one of the eaves of the car, illustratingthe manner of securing the side edges of the roofing-plates. Fig. 4 isan enlarged detail, being a sectional view through the eaves oppositethe doorway. Fig. 5 is a sectional view of the roof at one of the endsof the car; and Figs. 6, 7, 8, and 9 are sectional details illustratingthe manner of connecting adjacent roofing-plates, showing the differentsteps of theoperation.

Referring to the drawings, lOindicates the sides of the car, and 11 theends thereof.

12 indicates the doorway.

lins.

15 indicates a board roof which is carried by the purlins in the usualway and is adapted to support the metal roof, as hereinafter described.

16 indicates the metal roof, and 17 the runhing-board.

13 indicates the carlines, and 14 the pur- 18 indicates the side plates,which are arranged in the usual way.

As best shown in Fig.2, the roof 15 projects a short distance beyond thesides of the car, and under such projecting portions 19 are placedfacia-boards 20, which are placed a short distance from the sides of thecar, as best shown in Figs. 3 and 4c. This arrange- 'ment is secured byplacing blockszl between the facia-boards and the siding, thus formingrecesses 22 between the upper portions of the facia-boards 20 and thesiding of the car, as shown in Figs. 3 and 4E. The inner upper edges ofthe facia-boards 20 are bevdo not positively engage thee'nds of theroofing-plates, as would be the case if a square corner were formed andthe ends of the roofing-plates were bent down over such square corners.The-beveling of the -facia-boards prevents a positive or relativelyunyielding contactbetween the inner corners ofthe faciaboards and theends of the roofing-plates. Consequently the movement of the faciaboardscannot possibly be transmitted to the roofing-plates, which aretherefore relieved from any possible wrenching strains.

The construction above the doorway is shown on a larger scale in Fig. 4,from an inspection of which it will be seen thatowing to the necessityof making provision for the sliding door instead of using the thinblocks 21 I provide thicker blocks 23 at suitable points at oppositesides of the door-space, so that the faciaboards 20 are held at agreater distance from the sides of the car than at other points. (SeeFig. 1.) The manner in which the facia-boards are secured in place isnot essential, as all that is necessary is to so secure them as toprovide recesses 22 to receive the ends of the roofing-plates.

As illustrated in Fig. 1, the metallic roof is composed of a number ofroofing-plates 24, which extend from one side of the car to the otherand are connected together so as to form water-tight joints. In order tosecure satisfactory joints, I'em ploy the construction illustrated inFigs. 6 to 9, inclusive. From an inspection of Fig. 7 itwill be seenthat the adjacent edges a b of the roofing-plates are bent upward, so asto lie parallel with each other and spaced a short distance apart.Between the adjacent edges a b ofeach pair of roofing-plates lies a thinintermediate plate 25, as best shown in Fig. 7, which plate has an edgebent at right angles, as shown at c in Figs. 6 to 9, inclusive, whichedge is secured to the board roof by nails or screws 26 and lies underone of the metal roofing-plates. When the parts are assembled and beforethe joint is formed, they occupy the position shown in Fig. 7. When theparts are thus assembled, the upper portion of the plate 25 with theadjacent edge I) of one of the roofingplates is bent over the upper edgea of the other roofingplate in the manner shown in Fig. 8. Theupwardly-projecting parts are then foldedagain, in the manner shown inFig. 9, so that the upper portion of the edge a is bent over and liesoutside of and incloses a portion of the edge I) and the upper edge ofthe plate 25. In order to compensate for the shortening of the plate 25and edge 5 by bending in the mannerdescribed, the parts are made ofdifferent lengths-that is to say, the upturned edge I) is made longerthan the upwardly-projecting portion of the plate 25, the latter in turnbeing longer than the upturned edge a. By this construction the adjacentedges of the roofing-plates are firmly locked together and are alsofirmly secured to the wooden roof through the plate 25. Furthermore, avery firm water-tight joint is thus secured.

At their lower ends the metal roofing-plates 24 are provided withprojecting ends, which are bent over the side edges of the wooden roof,as shown in Figs. 3 and 4, and project into the recesses 22, lying incontact with the beveled portions of the facia-boards 20, as shown. Theends 26 of the roofing-plates lie loosely in the recesses 22, so thatwrenching strains of the car-body are not com municated to them. Themetallic plates at the ends of the roof are secured by bending theirside edges down over the end facia-boards 27 andsecuring them thereto bynails or screws 28, as shown in Fig. 5.

By this construction I provide a very secure metallic roof, which is notonly watertight, but is also so secured in place as to be capable ofadapting itself readily to wrenching strains, and consequently is notreadily damaged.

7 That which I claim as my invention, and desire to secure by LettersPatent, is

1. In a car-roof, the combination ofsupporting devices, roofingplatescarried thereby, said roofing-plates having projecting ends, andfacia-boards secured to the sides of the car below the supportingdevices, the upper ends of said facia-boards being slightly removed fromthe sides of the car, thereby forming recesses adapted to receive theends of the roofing-plates, substantially as described.

2. In a car-roof, the combination of supporting devices, roofing-platescarried thereby, said roofing-plates having projecting ends. andfacia-boards secured to the sides of the car, the upper ends of saidfacia-boards being slightly removed from the sides of the car, therebyforming recesses adapted to receive the ends of the roofing-plates, theupper inner edges of said facia-boards being beveled, to prevent thewrenching strains of the carbody being imparted to the projecting endsof the roofing-plates, substantially as described.

3. In a car-roof, supporting devices having portions projecting over thesides of the car, roofing-plates resting thereupon, said plates suitablyattached to the supporting devices and having ends extending over theprojecting portions of the said supporting devices, and side facia-boards arranged below the projecting portions of the supporting devices andforming recesses at the eaves of the car, said ends of theroofing-plates extending within the recesses and between the projectingportions of the supporting devices and top of the facia-boards.

4. In acar-roof, supporting devices having portions projecting over thesides of the car, roofing-plates resting thereupon, said plates suitablyattached to the supporting devices, and facia-boards beveled at theirupper edges, said bevel extending inward and arranged below theprojecting portions of the supporting devices and forming recesses, saidends of the roofing-plates extending within the recesses and between theprojecting portions of the supporting devices and the beveled edges ofthe facia-boards.

5. In a car-roof, supporting devices having portions projecting over thesides of the car, roofing-plates resting thereupon, said plates suitablyattached to the supporting devices, facia-boards beveled at their upperedges, said bevel extending inward and arranged below the projectingportions of the supporting devices and forming recesses, said ends ofthe roofing-plates extending within the recesses and between theprojecting portions of the supporting devices and the beveled edges ofthe facia-boards, and means for securing said facia-boards in position.

6. In a car-roof, supporting devices having portions projecting over thesides of the car, facia-boards suitably connected to the car, androofing-plates mounted upon the supporting devices and having projectingends, said projecting ends extending around the projecting portions ofthe supporting devices and between the facial-boards and the sides ofthe car.
